The portal view for tasks previously listed all task of all projects
without grouping them. It was a problem, mainly when we want to make
the distinction on project label_tasks, to make the difference
between tasks, issues, ... Grouping task by project by default allows
to show the label_tasks before each project.
Grouping the tasks removes the possibility to define a primary
ordering. We want to be able to ungroup the tasks in some cases.
The implentation was done in the portalsearch bar adding
a group by option. The portal proposes two grouping options,
project (by default) and none (to keep strict ordering).
